P-valuea
Mono-radicular teeth 72 0.72 (0.61) 5.45 (4.41) 0.982
Pluri-radicular teeth 23 0.73 (0.74) 5.64 (5.42)
Total 95 0.72 (0.71) 5.53 (5.19)

a Statistical significance level was defined at P = 0.05.
N = total number of tooth extracted, with mono-radicular and pluri-radicular teeth.
t-test was performed to compare the mean bone loss between mono- and pluri-radicular teeth.
